feat: LLM-powered search with free-text query, filter toggles, and auto-generated guide
- Search box: type anything, toggle filter pills (hybrid, price range, distance, etc.) - Backend calls Anthropic to parse query into search params - Playwright crawls Craigslist, CarGurus, AutoTempest with dynamic URLs - Results scored/ranked with car-specific scoring engine - Second Anthropic call generates a custom buying guide from actual results - Guide sections: top picks, checklist, mechanics, negotiation, budget - All visible live in the browser panel via noVNC
